Abstract

Smart materials have received increasing attention in recent years for their great potential to revolutionize engineering applications and design. The technological advantages of using smart materials over traditional materials arise from special capabilities due to unique micro structure or molecular properties. Among different smart materials like piezoelectric, electro-strictive, Magneto-strictive, magneto-rheological and electro-rheological, shape memory alloy seems to be probable candidate for semi-active control of different structural members in view of the fact that it generates a relatively large deformation and then recover upon heating.
